Abstract

Photorefractive (PR) crystals are widely investigated materials for all-optical signal processing.1 Fe-doped KNBO3, because of its high electro-optic coefficients2 and good photoconductivity, has been shown to have large photosensitivities in the blue-green spectral range.3 Since the response time of the photo-induced refractive-index changes is inversely proportional to the intensity it is of great interest to confine the interacting beams within a waveguide. Ion implantation has been shown to be well suited for producing waveguides in ferroelectric oxides such as BaTiO3 and KNBO3.4
